Description

Technical Field

[0001] The invention belongs to the technical field of human body sampling devices, and in particular relates to an artificial insemination and endometrial sampling device with uterine cavity visualization. Background Art

[0002] An endometrial sampler is a device used to extract samples from the endometrium, usually for medical research or diagnosis. The endometrial sampler can obtain different types of samples, such as exfoliated cells, secretions, and cell fragments, by sampling at different stages of the menstrual cycle to better understand the physiological and pathological changes of the endometrium.

[0003] The endometrial sampler usually consists of a sampler with a handle and a drill that can rotate. On the 12th to 14th day of the menstrual cycle, usually 7th to 10th day before the next menstrual period, the doctor or nurse can use the endometrial sampler to take a sample from the endometrium and then put it into a special sample collector. The sample can be further analyzed in the laboratory using various reagents to understand the physiological and pathological changes of the endometrium.

[0004] The artificial insemination tube is a tubular medical device, usually made of silicone or plastic, with a suitable length and tissue to keep the sperm alive and active during the delivery process. When using the artificial insemination tube, it needs to be inserted into the posterior fornix of the vagina to inject semen. In order to ensure accurate insertion of the artificial insemination tube, a vaginal speculum needs to be used to open the vagina.

[0005] The main body of the artificial insemination tube and the endometrial sampler are both tubes, and the working environment is similar. In order to improve the practicality and convenience of medical devices, the artificial insemination tube and the endometrial sampler can be combined into an instrument that can realize both artificial insemination and endometrial sampling functions, so that doctors can complete multiple different tasks with one functional instrument. At the same time, in order to improve the accuracy of sampling work, the instrument also needs to be given a visualization function to facilitate doctors to determine the orientation of the instrument. Summary of the invention

[0006] The purpose of the present invention is to provide an artificial insemination and endometrial sampling device with uterine cavity visualization to solve the problems raised in the above-mentioned background technology.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1 - Figure 6 As shown, a uterine cavity visualized artificial insemination and endometrial sampling device comprises:

[0031] A mounting head 1, a main pipe 3 and a secondary pipe 4 are fixedly connected to the side wall of the mounting head 1, a protective pipe 2 is sleeved on the main pipe 3 and the secondary pipe 4, a side hole 8 is opened at the end of the main pipe 3, an inner bend 9 is opened inside the mounting head 1, and the inner bend 9 is connected to the secondary pipe 4;

[0032] A push-pull rod 5, which is slidably inserted into the main pipe 3, one end of which is fixedly connected to a handle 6, and the other end of which is fixedly connected to a piston 7, and the piston 7 is slidably connected to the main pipe 3;

[0033] The endoscope 19 has a lens tube 20 fixedly connected to its end, and the lens tube 20 is plugged into the auxiliary pipe 4 via the inner bend 9. The endoscope 19 can be a mature model of the prior art, and the lens tube 20 can be plugged into the auxiliary pipe 4.

[0034] As can be seen from the above, when the medical staff needs to accurately collect the patient's endometrial sample, the lens tube 20 can be inserted into the auxiliary pipe 4 through the inner bend 9, and then the main pipe 3 and the auxiliary pipe 4 are simultaneously inserted into the patient's uterus. The end of the lens tube 20 is close to the end of the main pipe 3. The medical staff can accurately understand the insertion position of the main pipe 3 through the image feedback from the lens tube 20, which is convenient for the medical staff to align the side hole 8 with the area to be collected according to the feedback image, bring the main pipe 3 close to the endometrium, pinch the handle 6, pull outward and rotate the handle 6, and drive the push rod 6 to push ... The pull rod 5 and the piston 7 rotate and move outward, and the moving piston 7 forms a negative pressure environment inside the main pipe 3, and the endometrium enters the main pipe 3 from the side hole 8 to complete accurate sampling. Similarly, when performing artificial insemination, the main pipe 3 and the auxiliary pipe 4 are inserted into the appropriate position of the vagina through the image fed back by the lens tube 20, and the handle 6 is pushed inward and rotated, driving the push-pull rod 5 and the piston 7 to rotate and move inward, and the moving piston 7 forms a pressurized environment inside the main pipe 3, forcing the semen inside the main pipe 3 to flow into the vagina through the side hole 8, completing the artificial insemination operation.

A plurality of obliquely arranged clamping blocks 11 are fixedly connected to the end of the guide tube 10 , and a collar 12 is threadedly connected to the outer wall of the guide tube 10 .

[0036] In order to prevent the lens tube 20 from rotating inside the auxiliary pipe 4 and causing the transmitted image to shake, the medical staff can rotate the ring 12 to press against the clamp 11, forcing the inclined clamp 11 to bend and deform. Multiple bent and deformed clamps 11 will be clamped on the outside of the lens tube 20, and the rotation of the lens tube 20 will be limited by the friction between the clamp 11 and the lens tube 20.

[0041] The endoscope 19 has a lens tube 20 fixedly connected to its end, and the lens tube 20 is plugged into the auxiliary pipe 4 via the inner bend 9. The endoscope 19 can be a mature model of the prior art, and the lens tube 20 can be plugged into the auxiliary pipe 4.

[0042] As can be seen from the above, when the medical staff needs to accurately collect the patient's endometrial sample, the lens tube 20 can be inserted into the auxiliary pipe 4 through the inner bend 9, and then the main pipe 3 and the auxiliary pipe 4 are simultaneously inserted into the patient's uterus. The end of the lens tube 20 is close to the end of the main pipe 3. The medical staff can accurately understand the insertion position of the main pipe 3 through the image feedback from the lens tube 20, which is convenient for the medical staff to align the side hole 8 with the area to be collected according to the feedback image, bring the main pipe 3 close to the endometrium, pinch the handle 6, pull outward and rotate the handle 6, and drive the push rod 6 to push ... The pull rod 5 and the piston 7 rotate and move outward, and the moving piston forms a negative pressure environment inside the main pipe 3, and the endometrium enters the main pipe 3 from the side hole 8 to complete accurate sampling. Similarly, when performing artificial insemination, the main pipe 3 and the auxiliary pipe 4 are inserted into the appropriate position of the vagina through the image fed back by the lens tube 20, and the handle 6 is pushed inward and rotated, driving the push-pull rod 5 and the piston 7 to rotate and move inward, and the moving piston 7 forms a pressurized environment inside the main pipe 3, forcing the semen inside the main pipe 3 to flow into the vagina through the side hole 8, completing the artificial insemination operation.

A plurality of obliquely arranged clamping blocks 11 are fixedly connected to the end of the guide tube 10 , and a collar 12 is threadedly connected to the outer wall of the guide tube 10 .

[0044] In order to prevent the lens tube 20 from rotating inside the auxiliary pipe 4 and causing the transmitted image to shake, the medical staff can rotate the ring 12 to press against the clamp 11, forcing the inclined clamp 11 to bend and deform. Multiple bent and deformed clamps 11 will be clamped on the outside of the lens tube 20, and the rotation of the lens tube 20 will be limited by the friction between the clamp 11 and the lens tube 20.
